How Is Cardboard Recycled? Understanding the Process
Cardboard recycling plays a key role in managing waste and supporting sustainability in the UK. More than 70% of cardboard is recycled here. By turning waste into new products, we can reduce our environmental impact. It’s vital for anyone using cardboard packaging to know how it’s recycled.
The recycling of cardboard goes through six steps: collection, sorting, shredding and pulping, filtering, drying, and making new corrugated board. Cardboard fibres are strong and can be reused up to 20 times. Recycling not only saves resources but also cuts energy use by 25% to 50% compared to making new cardboard. Plus, it slashes water use by nearly 99% during recycling.
The Importance of Cardboard Recycling
Cardboard recycling is key to using resources wisely and keeping our economy efficient. It keeps valuable materials out of dumps. By recycling rightly, we maintain the quality of materials. This helps lower the chance of them getting polluted, benefiting our economy.
Understanding Recycling as a Resource
Recycling is a way to save resources. Cardboard recycling saves important materials and helps the environment. It saves up to 7000 gallons of water for each ton recycled. This shows how much it can help save resources. Also, it cuts down the harmful gases that go into the air from dumps.
Recycling cardboard uses much less energy than making new materials. This saves money and cuts down on oil and gas use. Plus, recycling a ton of cardboard cuts a ton of carbon dioxide emissions. This is good for fighting climate change.
Current Recycling Rates in the UK
About 71% of paper and cardboard gets recycled in the UK, making up 3.8 million metric tons each year. This great outcome shows our recycling system works well and people are involved. SL Recycling is a company that recycles about 92% of what they collect. This highlights the important role such organizations have in boosting recycling.

How Is Cardboard Recycled?
Cardboard recycling follows a detailed process, involving different groups in collecting and processing the waste. It shows how we can reuse cardboard to make new boxes and packaging. By following each step of the process carefully, we help our environment and economy.
The Six Steps in the Recycling Process
The process of recycling cardboard involves key steps. These ensure the cardboard keeps its good quality as it is reused. The steps are:
- Collection: Cardboard is gathered from homes or businesses that throw away a lot of it.
- Sorting: At a recycling centre, the cardboard is sorted. This is to take out things like plastic tape or metal bits.
- Shredding: Then, the sorted cardboard is shredded to get it ready for the next step.
- Pulping: The shredded pieces go through pulping. This is where the fibres are cleaned of any leftover unwanted materials.
- Cleaning and Filtering: The pulp is cleaned to make sure there are no impurities. This makes the recycled material high quality.
- Drying and Finishing: The last step is drying the pulp and pressing it into sheets. These sheets are then used to make new cardboard items.
Sorting and Collecting Cardboard
Good waste collection is crucial for cardboard recycling. It’s important to keep cardboard separate from non-recyclable stuff. Ways to collect cardboard include:
- Recycling bins at home just for cardboard.
- Working with companies that produce lots of cardboard waste.
After collection, the cardboard goes to recycling centres for careful sorting. Here, ordinary cardboard is separated from coated or waxed types that need special handling. Being careful in sorting improves the recycled material’s quality and supports eco-friendly efforts.
Step-by-Step Breakdown of the Recycling Process
Let’s dive into how old cardboard gets turned into new items. We start with shredding and pulping, move on to filtering and cleaning, and finish with drying. Each phase is key to making sure the new product is up to standard.
Shredding and Pulping the Cardboard
In the beginning, the cardboard is shredded into fine pieces. This makes the pulping process work better. When mixed with water and chemicals, we get a slurry. This step is crucial for breaking down fibres and getting rid of dirt.
Filtering and Cleaning the Pulp
After making the pulp, it’s thoroughly filtered and cleaned. Special filters catch bits of plastic and metal. This ensures that the pulp is free from any rubbish. Techniques like spinning help separate these bits, while special chemicals remove ink. This makes the pulp clean and ready for making paper.
Drying and Finishing the Material
Next, the pulp is dried on large belts and heated areas. This step cuts down the pulp’s moisture. The dry pulp is then pressed into sheets. These can vary in thickness for different uses. Finally, we get large paper reels, all set to be made into cardboard again.
Environmental Benefits of Recycling Cardboard
Recycling cardboard is not just responsible; it brings many environmental benefits. These benefits help sustainability greatly. By saving energy and reducing landfill waste, recycling lessens our impact on Earth.
Energy and Resource Conservation
Recycling cardboard saves a lot of energy. It uses 25% to 50% less energy than making new cardboard. This means we use fewer resources, up to 100% less. Also, recycling a ton of cardboard can save up to 7,000 gallons of water. This helps with water scarcity and resource management.
Reduction of Landfill Waste and Emissions
Recycling cardboard greatly reduces landfill waste. For every ton recycled, we save about 9 cubic yards of landfill space. It not only reduces waste but also cuts down methane emissions. Methane is a greenhouse gas warming our planet.
By recycling, we also reduce cardboard production’s carbon footprint. Keeping cardboard out of landfills tackles environmental challenges. It’s a big win against global warming.
| Benefit | Impact |
|---|---|
| Energy Savings | 25% to 50% less energy needed for recycling than virgin processing |
| Water Conservation | Up to 7,000 gallons saved per ton of recycled cardboard |
| Landfill Space Saved | About 9 cubic yards per ton of cardboard recycled |
| Reduction in CO2 Emissions | Around 1 ton of CO2 emissions reduced per ton of recycled cardboard |
| Trees Saved | Up to 17 trees saved for every ton recycled |
| Sulfur Dioxide Reduction | 50% reduction in pollution compared to the production of new cardboard |
By recycling cardboard, everyone contributes to a healthier planet. This helps save energy and reduces landfill space. Doing so ensures we use our resources wisely, aiming for a sustainable future.
Comparison: Virgin vs Recycled Cardboard
The discussion about virgin vs recycled cardboard brings out important sustainability aspects. We need to look closely at both types of fibres to understand these differences.
Understanding Virgin Fibres
Virgin fibres come from new wood, treated to remove complex compounds like lignin. This process ensures high-quality, strong materials for tough uses. However, this choice raises issues like deforestation and high energy and water use. Today, there’s less 100% virgin cardboard as companies aim for greener options.
The Advantages of Using Recycled Fibres
Recycled fibres come from used cardboard and can be reprocessed many times. They help save virgin resources, pushing us towards sustainability. They also help cut down deforestation, a key point for eco-minded businesses. Although recycled papers can be weaker, their environmental benefits win.
Companies now prefer eco-friendly materials, meeting the demand for sustainable packaging. Innovations like Grupo Modelo’s CanCollar show how the industry embraces recycled materials to decrease plastic use. For more details on these material differences, click here.
Conclusion
Cardboard recycling plays a crucial role in keeping our planet healthy. Every year, the U.S. uses over 80 billion corrugated cardboard boxes. Understanding how recycling works is key.
By recycling, we save energy. It takes only 75% of the energy to recycle cardboard compared to making new ones. This choice is wise and efficient.
Recycling cardboard reduces waste and supports a circular economy. With a high recycling rate of 92.9%, there’s room for improvement. Just one ton of recycled cardboard saves as much energy as 46 gallons of oil. It also keeps 9 cubic yards of landfill space free.
Thus, recycling cardboard makes a big difference for businesses and individuals alike. It saves money and cuts down on energy use. Every step we take leads to a sustainable future.
